Hi, I wonder why I get those ugly artefact on my modèle when I use Rendered display. My curve seems to be clean, All points are on the same X plane, I used _PlanarSrf.
If someone can help me, thank you.
Hi @Fabrice_Chapot
Without seeing the file, my initial guess would be that the render mesh is too coarse. Try setting it to Smooth and Slower. If that doesn’t work, post the offending file.
HTH, Jakob
Thank Jacob, Smooth and Slower doesn’t works for me. Here’s the file.
Thank you !

I see this all the time, it’s some kind of artifact with the Ambient Occlusion.
It seems to be hard to get rid of short of just not using that. Reducing the effect requires messing with the shadow settings under the view mode options. Based on my experimenting right now what reduces it is reducing the “Skylight shadow quality” and setting some value for the “Camera Based Clipping Bubble” options.
Okay JimCarruthers, that visually eliminates the problem, but does that mean there’s no problem with the model?
Thank you for your help
I don’t think this has anything to do with ambient occlusion (switching AO off doesn’t resolve the problem) but with your objects being very far from the origin.
placing them closer to the origin results in completely artifact-free shading:
no messing with the display mode settings needed.
(the circle in the images is a conrol object I put in)
No there’s no problem with the model.
How did you “switch off the AO?”
By selecting “default lighting” in the rendered display mode settings.
And I swear to God that when I tried this the first time, nothing happened, but I re-tried it a couple of minutes ago and you are right, the artifacts disappear. (don’t exactly know why this didn’t work before)
So yes, your assessment that this is related to AO seems to be correct.
But more importantly, as I said, moving the objects closer to the origin completely resolves the issue altogether.

Thank you all, I’ve tried both solutions and it works perfectly. I think the way to be close to 0,0,0 is enough, no need to switch off OA lighting, despite it works too.
Thank you guys !
